Unite "My present'inventi'on relates to awindo'w structure for 'closing a window 'opening in zthe 'w'all of a "building for admission of light and air. v

This application is a continuation-'impart 'of my application Ser. No. 60,127, led November 15 1948, 'for window structure, and which 'has now -1become 'abandoned. Y

It is an object of this invention to provide an improved window structure with two spaced glass panes 'in a single or double metal sash mounted for swinging .movement in a 'rectangular frame to be mounted with two of its "sides in vertical position and with its other two sides 'as bottom and top, respectively, y.in a window opening ain lthe 'wall 'ofa building foradmission o'flight and air.

Another object of this invention is to provide an .improved window structure of 'the aforesaid kind incorporating 'a 'Venetian or other blind mounted on 'the swingable metal sash inside its top so as to be lowered'and raised in the space between the glass panes.

Further objects of this invention and advantages gained thereby will appear from the following description of a 'preferred form of the invention illustrated in the accompanying drawings in which:

jFig. 1 is a diagrammatic view of a window wlith frame and sash, Vin which `the sash. is mounted for 'swinging movement in the frame through an=angle of about 180 Iabout amedian horizontal axis, ,thesash bein'gflshownias having been swung from shut position with bottom out- Wards and top inwards through a'small `angle to a ventilating position.

Figs. 2, 3 and 4 are cross sectional views on a larger scale taken substantially on the lines II-IL III-III and IV-IV, respectively, in Fig. 1, but with the sash in shut position, the sash being a double sash composed of an innr sash pivoted to the frame for swinging movement therein, and an outer sash hinged at bottom to said inner sash for swinging movement therewith and in relation thereto.

Figs. 5 and 6 are fragmental front views showing the lower right corner and the upper right corner, respectively, of the window as viewed from inside the building having in its wall the window opening closed by the window.

Fig. 7 is a fragmental sectional view taken substantially on the line VII-VII in Fig. 6.

Fig. 8 is a fragmental sectional view taken substantially on the line VIII- VIII in Fig. 7.

They rectangular window frame 10, which is to be mounted with two of its sides in vertical position and with its two other sides as bottom and top, respectively, in a window opening in the wall of a building, may be constructed from metal or from wood as may be desired. The sash, generally denoted 11 in Fig. l, is to be furnished with two spaced glass panes 12 and 13 (Figs. 3-6) and preferably consists of a double sash composed of an inner sash furnished with the inner glass pane 12 and pivoted to the vertical sides of the frame for swinging movement therein through an angle of abo-ut 180 about a States Patent ice 2 'median horizontal axis, and an outer sa's'h furnished with the outer glass pane 13 and hinged at 'bottom to theinner r,sash lfor'swinging movement therewith and in relation thereo. Means for pivoting the inner sash to the vertioal lsides of the frame'10and means for hinging the outer sash to the inner sash .are provided -but are not vshown 'on the drawings and will not be described herein because such means of different constructions are'well known in fthe art and do not 'form part of this invention.

The inner sash kfurnished with the inner .glass pane ..12 is composed of a one-piece Vbar of .rolled `or extruded metal, preferably aluminum, rbentto U-shaped .formation with rounded corners 14-(see Figs. l and 5) between yits bottom portion A15 .and vintegral Alegs A16 forming bottom and vertical sides, respectively, of said sash, and a straight sash .top metal rail 17 `extending between the free endsof said legs `16 and .forming 'right angles with -them ('-see Fig. 6) and being .detachably secured at 'its 'ends to said `free ends of `said legs .16. The detachable sash top rail 17 has a depending ilange 18 forfhiding ya blind, preferably a Venetian blind, to bemounted on said top rail 17 inside thereof and -behind said *depending ilange y18 (Figs. y2 and 6), so that the blind may be lowered and raised in the space between the two glass `panes 12 and 13. Re-

lcesses, preferably VTin vthe form of grooves, for receiving fthe edges of the inner glass pane 12 are provided in the linside of said lU`forniation comprising lthe inner fsash bottom portion I5 'and the integral legs 16, and .inthe Yfree edge portion of the depending V-ilange 18 of th'e yinner sash top rail 17, said grooves vbeing denoted L19 corners between its bottom portion A2-1 and integral legs .22 forming :bottom and vertical sides, respectively, ofthe outer sash, and .a straight outer sash top rai'l 23 vextend- .ingbetweensand I'detachably secured to thefree ends fof `the legs 22 and forming ,right angles 'withthem Also the outer sash ytop rail 23 is provided vwith a `depending :flange 24, whereby -the blind 'to fbe mounted ion .the

1inner sash top'rail inside thereof will be housed between the depending flanges 18 and 24 of the inner sash and the outer sash, respectively. Grooves 2S and 26 for receiving the edges of the outer glass pane 13 are provided in the inside of the U-shaped formation comprising the bottom portion 21 and the integral legs 22 and in the free edge portion of the depending flange 24, respectively.

In the preferred form of the invention shown on the drawings the cross sectional shape of the inner sash top rail 17 is that of a hat section with a crown portion 17a Iand front and rear brim portions 17b and 30 respectively, and with a veil hanging from the front end of the front brim portion and forming the depending ilange 18. The crown portion 17a forms a groove for receiving a mounting bar 27 of channel shape for a Venetian blind 28, as shown in Fig. 2.

In the preferred form of the invention the outer sash top rail 23 comprises a strip-shaped portion 29 fitting over the rear brim portion 30 of the hat section of the inner sash top rail 17, and a flange 31 projecting upwards of the U-shaped formation of the inner sash. Figs. 6 and 7 show the fastening at the right upper corner of the sash. The U-shaped formation of the inner sash is provided in -its outside with a groove 33 (see Figs. 2, 3 and 4), and at the free end portion of each of the legs 16 there is inserted and secured in this' groove 33 one leg 34 (Figs. 6 and 7) of an angle-shaped member whose other leg 3S projects towards the other leg 16. The top rail 17 is fastened to the leg 35 by screws 36.

The means for fastening the detachable outer sash top rail 23 between the legs 22 preferably comprises lugs 37 (shown in cross section in Fig. 7) projecting from the ends of the depending ange 24 into the grooves 25 at the free end portions of the legs 22 and fastened to them by screws 38.

On the outside of the portions of the legs 16 extending above the pivotal axis of the inner sash there are mounted preferably wooden ribs 39 (Fig. 3)y for abutting corresponding abutments 40 on the inside of the vertical portions of the frame 10, and on the inside of the portions of the frame below said axis there are provided similar ribs 41 (Figs. 2 and 4) for abutting corresponding abutments 42 on the inner sash. The ange 31 projects up between the coacting abutment means 32 and 42 of the inner sash top rail 17 and the top of the frame, respectively, whereby the outer sash will be safely held to the inner sash when shut.

The shown and described construction of the sashes unites easy manufacture, small weight, high strength and stability and excellent durability of the sashes and a neat appearance of the window even if equipped with a Venetian or other blind to be lowered and raised in the space between the glass panes. The construction is advantageous also by permitting easy renewal both of the blind and of the glass panes.

What I cla-im and desire to secure by Letters Patent is:
